Slim Case Design
While officially the M20 comes in at 42mm in diameter, the case shape makes the watch feel much smaller. Don't let its good looks deceive you: the M20 is durable and adventure-ready, with an off-set screw-down crown that won't bite your wrist and 200M-rating.

The GMT Function
The M20 GMT features a precise, Swiss-Made quartz GMT movement — GMT time, or any second time zone, can be easily read, using the red GMT hand and the 24-hour scale around the outside edge of the dial. A third timezone can then be read by rotating the 24-hour bezel. The GMT complication was originally created for pilots who needed to track multiple time zones, but was quickly adopted by businesspeople and explorers alike.

Great tool watch
I work in LE and am a military reservist. I worry about wearing automatic watches in these two occupations for obvious reasons. Wanted a quartz gmt. This watch was the perfect answer. I wish the bracelet had screw links, but I may upgrade the bracelet anyway. Very pleased with the purchase.

GMT
Very good. Delivery was fast. Quality is excellent and for the price, it would be hard to beat. Definitely recommend.

M20 GMT
Love this watch! Fit and finish is great, accuracy is very good! I wear this all the time, motorcycle adventure travel, swimming, shooting pistols … this is a great hard use watch!

Excellent watch!
I absolutely love this watch! It was a bit of a learning curve to get used to adjusting it. I love the content on your YouTube channel but I couldn’t find a video that helped a bit more with setting the GMT movement.
